WARNING: Before working on, or disassembling the Hydrant (including removing any bolts(s) holding the Hydrant together), shut off gate valve to isolate Hydrant from main water source. Loosen (do not remove) one nozzle cap two turns and check for water under pressure inside Hydrant - bleed off any pressure, then remove nozzle cap completely. Open Hydrant main valve completely. A continuous flow of water, no matter how slight, indicates Hydrant is not properly isolated from the main water supply, and that problem must be corrected before any Hydrant disassembly can proceed. Disassembly of Hydrant with pressurized water acting against the main valve could result in unexpected ejection of Hydrant parts, debris or high-pressure water stream, which could cause serious bodily injury.

SuperCenturion250FireHydrantwas introduced. Some models of the SuperCenturion200FireHydrantcontinue in production. The Super Centurion200FireHydrantreplacedthe Centurion Weather Cap with a Weather Seal on the Hold-Down Nut.In2011,theflatgasketusedat the Ground Line connection was replaced by an O-ring seal.

Super Centurion 250TheMuellerSuperCenturion250FireHydrantwasintroducedin1997and continues in production. The SuperCenturion250FireHydrant

Sinceitsintroductionin1975,there have been 3 models of the Centurion Hydrant; Centurion, Super Centurion 200 and Super Centurion 250.

CenturionThe Mueller Centurion Fire Hydrant wasproducedbetween1975and1986.

Super Centurion 200TheMuellerSuperCenturion200Fire Hydrant was introduced in 1987andreplacedtheCenturionFire Hydrant. It continued in productionuntil1997whenthe

ispressureratedfor250psi.Keyfeatures include an O-ring seal at BonnetandGroundLineconnection,a Reversible Main Valve and a Stainless Steel Stem Coupling. The CenturionandSuperCenturion200Fire Hydrant use 2 bolts to attach the Drain Ring Housing to the Lower Barrel.TheSuperCenturion250Fire Hydrant eliminated the bolts and uses 2 of the Barrel-to-Shoe bolts to hold the Drain Ring Housing in place.

WARNING: Before removing any bolt(s) holding the Hydrant together, shut off gate valve to isolate Hydrant from main water source. Loosen (do not remove) one nozzle cap two turns and check for water under pressure inside Hydrant – bleed off any pressure, then remove nozzle cap completely. Open Hydrant main valve completely. A continuous flow of water, no matter how slight, indicates Hydrant is not properly isolated from the main water supply, and that problem must be corrected before any Hydrant disassembly can proceed.

CAUTION: Always fill the oil reservoir with the Bonnet installed, the Hydrant in its normal upright position, and the main valve fully closed. If the Hydrant is filled with lubricant under any other circumstances, excess lubricate can overfill the Bonnet and create a pressure lock. This could result in damage to the seals or Bonnet or prevent proper Hydrant operation.

• Drains are clogged by some foreign material.

• Failure to leave Cap off of Hydrant to allow air to enter so Barrel will drain.

The foregoing procedure introduces full line pressure to Drain Valves. It provides the best method for cleaning Drain Valves using water pressure.

IMPORTANT - Initial installation of Hydrant MUST BE MADE PROPERLY so Traffic Flange will function properly. Hydrant should be blocked at ground line and around Shoe using concrete or similar substance to prevent ground from giving way when Hydrant is struck (see page 9-10).

For additional information on Hydrant anchorage,blocking,anddrainage,seeAWWAStandardC600andManualM17.

1. To ensure their readiness for immediateuse,itisrecommendedthat Fire Hydrants be inspected and tested at six-month intervals.

2. Inspect visually for damaged or missing parts.

preparation and instructions

The following procedure is recommendedtotouchup/repairhydrantscoatedwithAmercoat370fast dry epoxy coating to assure a goodfinish.1. Thoroughly clean the hydrant. Wash off any dirt or lose debris.2. Remove surface rust by wire brushing,sandblasting,etc.3. Roughen shinny surfaces with light sanding (to improve paint adhesion).4. Primer coat bare metal. Spot prime with one of these recommended spray primers:•Preferred – PPG Amercoat® 370(2-partepoxy)orAmercoat® One (single component epoxy). These expoxies can be ordered directly from PPG (see order form available on Mueller Co. website muellercompany.com).

•Optional – Rust-Oleum® brand CleanMetalPrimer,ProfessionalPrimer,RustyMetalPrimer,orRust Reformer Primer.

•Optional–Krylon® brand Rust Tough® Rust Preventative enamel.
